IP and LAN Protocol Support Network Layer - Routing Introduction This section highlights routing features and protocols supported by the Vanguard IP Applications Ware. Internet Protocol (IP) Routing The Internet Protocol is a connectionless packet delivery protocol that performs addressing, delivery, processing and control for transporting data packets over a network. Motorola's implementation of IP Routing supports these protocol and features: • ARP (Address Resolution Protocol) • RIP version 1 and version 2 (Routing Information Protocol) • On Demand RIP • OSPF • Default Gateway and Default Subnet Gateway • IP Broadcast Handling • IP Multicast Routing - IGMP (Internet Group Multicast Protocol) and DVMRP support • IP Address Filtering and Access Control • ICMP Router Discovery • Proxy Routing • Network Address Translation (NAT) • Class Inter-Domain Routing (CIDR) for OSPF and static routes In addition, Motorola IP implementation also offers bandwidth management solutions to maximize network performance and availability. These solutions offer: • Dial on demand routing • IP load balancing • Bandwidth on demand • Data compression • Bandwidth allocation • Time of Day link control • Traffic and Protocol prioritization OSPF The Vanguard supports Open Short Path First Protocol (OSPF) defined by RFC 1583 version 2. OSPF is an Interior Gateway Protocol (IGP) used to distribute information among routers belonging to an autonomous system (AS). Vanguard implementation of OSPF offers: • TOS routing - Packet routing based on Type of Service (TOS) • Variable Length Subnet Masks - Lets you break an IP address into variable size subnets, conserving IP address space. • Routing authentication - Provides additional routing security • CIDR - Classless Interdomain Routing • IP subnetting and the tagging of externally derived routing information. It uses IP multicast when sending or receiving packets. Introduction to Vanguard IP and LAN Feature Protocols T0100-01, Revision B 1-5 Release 5.4
